I would suggest Meetup.com
When you join (it’s free), you search by your own interests.
My boss went through a divorce and was lonely. I suggested it to him. He joined a sailing group.
The thing with Meetup is these people want to be around people who enjoy something they enjoy. There are photography groups, art, sailing, caving……the list is a mile long.

In order to find a really good friend, you’ll need to be one. Recognize people’s birthdays. Ask them about their weekend or recent trip. Join facebook and invite them. It grows from there. However, I can’t promise tons of great friends. I feel blessed to have ONE golden friend and several people I can laugh with and have coffee with. And my new job with increased hours has left my best friend a little lonely and missing me. I hate it. But I had to work more. I just try to squeeze in coffee…a quick text…a card in the mail…and an occasional gals evening.

Best of luck. Hang in there!
